Abstract (en)
The apparatus includes a telescopic double tubular member (2) accommodated in an outer case (1) that is mounted such as to surround an outer circumferential surface of a water pipe K, and placed from above between a pair of cut faces (10) formed by making a full cut of the water pipe K. The double tubular member (2) includes an anti-corrosion member (3) that faces the pair of cut faces (10) of the pipe and a core member (4) to be inserted into the anti-corrosion member (3) from above, and is configured such that the anti-corrosion member (3) is radially expanded by the core member (4) being inserted into the anti-corrosion member (3), so as to be pressed against the pair of cut faces (10) of the pipe. The anti-corrosion member (3) has a through hole (31) that communicates with the water pipe K, and a flange (35) positioned above the through hole (31) and extending radially outward. The flange (35) has an abutment surface that abuts on an outer circumferential surface of the water pipe K, and this abutment surface is curved along the outer circumferential surface of the water pipe K.
